Convert surface bodies to solid in Ansys
 

Hi. I'm trying to do a cfd simulation of the DrivAer model. But the outer body and underbody are modelled as a surface and since it's an iges file, I'm unable to convert it into a solid body in CAD . Now I'm unable to use boolean operation in Design Modeler to create a computational domain for cfd. Please help me convert these surface bodies to solids :)

You can try to combine the surfaces with space claim fix tab (if I'm not mistaken for the name)

Thank you! I was able to convert the surface bodies to solid by using the stitch, combine and other options under the "repair" tab in ANSYS Spaceclaim.
